Not different from Peruvian skins. 



The adnlt male has the base of the lower mandible white ; the back is of a 

 purer olive-green, the cheeks and ear-coverts are more blackish and the abdomen 

 clearer greenish than in the other specimens. 



This species has already been recorded for Brazil by Prof, von Ihering, who 

 received several examples from the Rio Jnrua.*

This species differs at once from C. auratus (Dum.) and its geographical races 

 by the bright scarlet (instead of orange) throat. 



The specimen mentioned by Pelzeln f as being intermediate between the two 

 species is, thanks to the kindness of Dr. Lorenz, now before me. It belongs 

 undoubtedly to C. amazonicus, and does not differ from average specimens of this 

 species, though the colour of the throat has faded into a rather paler scarlet, the 

 bird having been exposed to the light for a long time. The other examples obtained 

 by Natterer on the Rio Negro, agree with those from Teffe, except that the female 

 from Marabitanas has small black spots on the throat, this being uniform scarlet 

 in the female sent by Mr. Hoffmanns. 



Comte de Dalmas % has pointed out that C. amazonicus is the proper name of 

 the red-throated species, while the C. punctatus of the Catalogue of Birds ought 

 to be called C. auratus (Dumont). 



It may be interesting to say a few words about the geographical forms of the 

 orange-throated species, the distribution of which is very peculiar. In addition to 

 the fine series of the Tring Museum, which comprises most of the specimens 

 formerly in Comte de Dalmas' collection, I have before me the four examples from 

 Barcellos, Rio Negro, collected by Natterer, aud on studying this material I arrive 

 at the following conclusions.
